The letter, which was obtained by the Northwest Arkansas Democrat-Gazette, begins with the woman asking “if it were at all possible for me to marry my fiancé. It is very important to us (that) we get married soon so that we do not have to wait for his entire sentence to be wed.”

“Me and him have been together for nearly four years, two of which we have been engaged, so this is no spontaneous act we will regret later,” she added.

Roberts is currently in prison as she awaits her trial for the same charges that her boyfriend was convicted of.

Atchley, along with Justin Staton, 15, pleaded guilty to the murders of 66-year-olds Patricia and Robert Cogdell, who had raised Staton.

Another teenager, 19-year-old Hunter Drexler, was also charged in the killings and is still awaiting trial on capital murder.

Authorities revealed that the teens robbed and shot the older couple, and then discarded their bodies in a wooded area behind their residence.

Court documents indicated that Staton told police that he complained to Drexler about his grandparents and that his friend suggested that he kill them.

Atchley, who was present during the incident, told law enforcement officials that the plan had been formulated while he, Staton and Drexler were in juvenile detention together.

Authorities discovered the Cogdells’ bodies after a co-worker of Robert Cogdell’s from Maumelle’s Public Works Department became worried after he had not shown up for work.

“Anastasia advised that there was a plan to shoot and kill” the couple. “She and [Connor] planned to run away and were promised a BMW to use on their run,” an affidavit stated.

Police said that the female victim was sitting in the BMW when someone opened fire through a window.

Staton was sentenced to 35 years behind bars, despite the fact that he was facing a life sentence.

The Arkansas Department of Correction indicates that requests for marriage must first be sent to a chaplain and then needs approval by a warden.
